'We are witnessing a humanitarian tragedy in Gaza'

More than 800,000 people have fled to UN emergency shelters in central and southern Gaza, Juliette Touma of the UNRWA told Conflict Zone, adding that number exceeded her agency's "worst case scenarios." Touma says the coming winter will exacerbate already desperate circumstances in Gaza. Her agency, which cares for Palestinian refugees, has had more than 100 staff members killed in the conflict.
